Kṛṣṇa outlines the state of total spiritual absorption. When a person’s intelligence, mind, faith, and refuge are all fixed in the Supreme, they become fully cleansed of all misgivings and sins through the power of complete knowledge. Such a person proceeds straight on the path of liberation. This is ‘Apunar-āvṛttim’—the state of no return. They exit the cycle of material suffering forever. It is not enough to have a ‘hobby’ of spirituality; one must be ‘tat-parāyaṇāḥ’, meaning completely devoted and anchored. Every faculty of the human being must be dialed into the frequency of the Absolute. By being so focused on Kṛṣṇa, the past karma and mental stains (‘kalmaṣāḥ’) are simply washed away. Arjuna is being shown that the goal is not just to survive the war, but to use the war as a catalyst for this total mental absorption, which leads to the ultimate freedom of the soul.
